Abstract (en)
A media processing system and device 100 with improved power usage characteristics, improved audio functionality and improved media security is provided. Embodiments of the media processing system 100 include an audio processing subsystem 301 that operates independently of the host processor 304 for long periods of time, allowing the host processor 304 to enter a low power state. Other aspects of the media processing system 100 provide for enhanced audio effects such as mixing stored audio samples into realtime telephone audio. Still other aspects of the media processing system 100 provide for improved media security due to the isolation of decrypted audio data from the host processor 304.
